What was done
A PRISMA systematic review searched four databases (Cochrane, Web of Science, Medline, and PubMed) to determine how donor chronological age impacts the chondrogenic potential, osteogenic and adipogenic differentiation, cell surface characterization, and proliferation of mesenchymal stromal cells (MSCs). From 3,027 screened records, 14 studies met inclusion criteria.
What was found
The abstract reports no numerical values, pooled estimates, or effect sizes. Most included studies identified a clear association between advanced donor age and reduced MSC clonogenic and proliferative potential. In contrast, findings regarding the impact of age on chondrogenic, osteogenic, and adipogenic differentiation potential were conflicting and heterogeneous.
Why it matters
Understanding whether donor age impairs MSC chondrogenesis is critical for determining the viability of autologous cell therapies in older patients with degenerative joint disease. This review highlights that while cell expansion capacity declines with age, evidence for impaired chondrogenesis per se remains inconsistent.
Limits
The abstract provides no quantitative data or meta-analytic results. The included evidence base is small (14 studies) and limited to in vitro cellular assays with conflicting findings. Clinical in vivo outcomes were not evaluated.
